NowLearning is ServiceNow's own official training platform, offering courses mapped directly to the CAD exam objectives, produced by the company that builds the platform and writes the exam. As the official source, alignment with the exam is guaranteed, and the price — free — is hard to beat.
What NowLearning doesn't do is track your individual readiness over time. Content is organized in a fixed sequence with end-of-module checks, but there's no diagnostic upfront and no evolving prediction of your pass likelihood as you progress.
Edureify's curriculum is built on the same official material, but the Diagnostic identifies specifically which of Now Platform application development — forms, business rules, scripting, and workflows you're weakest on, and the roadmap keeps you there until your Readiness Score improves — which working through official modules in order doesn't measure.
